I learned a similar story in Pediatric Residency. As I learned it, toddler derives from TOT (a small measure of rum). When one was a TOTTLER, one drank too many tots and stumbled. An infant was a small measure of an adult and also stumbled like a tottler. Hence the terms Tot and Toddler.

Google searches through the decades have failed to find supporting evidence, but it is still a fun story to tell new parents (with a historic-accuracy disclaimer)

For me the toddler's story goes like this. Tod is a current Dutch word (sorry, I didn't invent it), tod means a rag or worthless piece of cloth. I always saw the English word toddler as a babe waddling in easy fabrics. Because of all the tumbling it does it is not worthwhile to dress it up in a smoking, tuxedo or fancy dress. So it hobbles around in easy non costly fabrics. * A tod als means a cherished piece of cloth or raggy cloth doll that a baby/toddler absolutely needs when it goes to sleep. Toddler and tod belong together.
